An entire forgotten corpus of US writing on the Nazi German enemy boomed in a matter of a few years, peaked during World War II, and collapsed within months of the war ending. For a fleeting moment in history, significant parts of the intellectual world in the United States converged to provide a cool-headed analysis of the Nazi threat and a clear identification of the enemy. Starting in 1944, these writers also offered an elaborate plan for a postwar re-education that would transform the National Socialist German nation into a democratic ally. Readers alarmed by the current resurgence of authoritarianism will learn from the work of those activists who analyzed Nazi Germany during World War II. This book, the first monographic study of this literature, provides pointed introductions to the main intellectual projects, their unique collaborative spirit, and their epochal results.
